PC for rendering and small 3D work within 50k

Hi guys, so one of my friend's PC fried out today, and he needs a PC immediately. He's taking courses with a lot of rendering so he needs a PC that would suit him in the long run. He's not doing too much intensive 3D work and he doesn't really play any games so I don't think he'll be needing any GPU right now. Can you guys suggest a good build within 50k? Thanks a lot.
